My invention relates to faucetssuch as are employed in connection withsinks, lava' tories, tubs, and the like and particularly to a faucet inwhich the movable parts are ar-' ranged as a unit which may be readilyremoved from the faucet body, the removable parts of the various faucetsof one type:

fective, a unit carrying' the movable parts of the faucet may be removedand a similar unit installed in place thereof.

The principal object of movable valve seat which may be readily removedfrom the unit and another one substitluted therefor.

The present application is a continuation in .part of applicants prioralpplication, Se rial No. 506,087, filed Oct. 7t i, 1921.

In the present embodiment of the inve-n` tion the removable seat isstamped from sheet metal which provides a cheap and satisfactoryarticle, although it is to be understood that it may be formed in anyother desired manner.-

In faucet structures such as that herein disclosed, it-is found thatwhen the washer becomes defective and the rwater iows through betweenthe washer and the valve seat for a considerable length of time, thevalve seat becomes scored so that difficult is experienced in making thevalve shut o even after'a new washer is put on.. With many of the olderfaucets it becomes necessary to throw away the entire faucet andreplaceA it with a new one due to the fact that the faucet was madeinoperative by the scoring of the valve seat.

In order to overcome this defect, certain structures having removablevalve seats were designed .such as shown in applicants priorl Patent No.1,148,441', granted July 27th, 1915. In the structure of this earlierpatent however, the valve seat was formed as a part of the removableVcollar of .the unit and thus the seat could not be replaced withoutreplacing the entire unit or at .fleast disassembling the entire unitand employing a new collar.

With the removable valve seat of the present invention, the valve seatmay be readily slipped oil' and a new one slipped on in the place of it.As a matter of fact with applicants new structure,-the valve seat may bereplaced by anew one as readily as the being all alike so that in case afaucet becomes dethe present invention is the provision, 1n a faucethaving a re-..- movable unlt as above descr1bed, of a re waal-1er canbe,- Thus. in applicants Vpresent structure, the removable unit 'may betaken out, a new washer inserted on the stem and a new valve seat'on thecollar thus providing for-all intents and purposes a new valve onthefaucet. with immaterial outla7 for parts and, labor.

vA' urther advantage of making the valve seat separate'is that the valveseat may be vmade of-ajsuperior relatively expensive ma- '.,terxal asphos horbronze while the sleeve .can be-made o a cheaper metal asbrass.T Be'ferring now to the drawings- Ifigrel is a section through onemodification .of applicants invention,

Figure 6 is a pers tiveview of the removable valve seat etached.

In the drawings, in which like reference characters indicate like partsin the several views, 10 indicates the valve casing having the nozzle11i extending therefrom. The valve casin 10 is provided with a. base 12adapted to secured to the tub or other device in the usual manner.Extendin downwardly from the base 12 is a threa ed pipe 13, whichcommunicates with the water or other system. Intermediate the top andbottom the casing 110V-is provided with a diaphragm 14, having'anopening through the center thereof through which the water or otherfluid may pass. The upper edge of the dia hragm 14 is beveled asindicated at 15.

cylindrical opening 16 is provided in the casing 10 within winch ispositioned the sleeve 17 of the removable unit. The sleeve 17 adjacentto the lower end thereof is inwardly offset as indicated at 18.- Aboutthe againstr which the valve washer or gasket 22 may engage assubsequently described.

The sleeve 17 is provided with the lateral openings 23 through which thewater passes to the chamber 24 surrounding the sleeve17 and with whichthe bore of the nozzle 1l communicates.

Within the cylindricalopenin 16 in the casing 10 and above the sleeve 1is an annular member 25 having at the opposite sides thereof thedownwardrllz7 extending tapered lu0s or cams 26. he upper' end of thecasing 10 is externally screw threadedk to receive the internal threadson the cap member 27 which, when screwedy down, forces the annularmember 25 and the sleeve 17 downwardly causing the converging vportionof the removable valve seat to snugly engage the beveled edge 15 of thecasing diaphragm 14.

Positioned within the sleeve 17 is the cylindrical block 28 providedwith valve operating stem 29 which extends outwardly throughthe'openings in the annular member 25 and cap 27, packing material 30being provided within the cap about the stem 29. The block 28 isprovided 1n the upper surface thereof with a pair of V-shaped notches31, adapted when thevalve 1s in normal closed position, to receive thecam lugs 26 of the annular member 25.

The block 28 and stem 29 are centrally bored as indicated at 32 toreceive the upper reduced end 33 of a secondary valve stem or valveplunger 34. The valve washer 22 is secured on the reduced lower end ofthe plunger 34 by means of the cup shaped retaining washer 35 and nut36.

Within the sleeve 17 about the plunger 34 is a coil compression spring37, one end of which engages the flange 38 on the plunger 34 and theother end engages the inwardly extending flange 39 on the sleeve 17.This spring 37 tends to return the 'valve washer 22 into engagement withthe valve seat 21 whenever the valve is opened.

Positioned within the sleeve 17 about spring 37, is a second heaviercompression spring 40, one end of which engages the inwardly directedportion 39 of sleeve 17, the other end being in engagement wlth block28. Spring 40 tends to return block 28 to its uppermost positionwhenever it is depressed. U

The operation of the faucet shown in Fi s. 1 to 4 is as follows: v

ue to the fact that the cap member 27 firmly engages the annular member25, the

member 25 is held stationary, thus when the stem 29 is rotated by theusual handle, the notches 31 in the block 28 are displaced in relationto the downwardly extending lugs 26 on the member 25 and the block 28 isforced downwardly, striking the shoulder at 38 on the stem 34 4andforcing the valve washer 22 ofl from seat 21. It will be understood thatthe springs 37 and 40 are both compressed by this operation. l s soon asthe valve operating handle is released, the spring 40 forces. the valveblock 28 upwardly into its normal position. At the same time,

the spring 37 tends to move the plunger 34 upwardly, this movement beingassisted by the pressure of the water in the stem.

Referring now to Fig. 5, which shows a modified form of spigot, thecasing 50 is substantially identical with the casing 10 of Fig. 1.Within the casing 50 is a sleeve 51. The sleeve l51 adjacent tothe upperend thereof is internally screw-threaded as shown at 52. Within thescrew threaded portion of the sleeve 51 is an operating plunger 53,provided with threads 54 adapted to co-oper'ate with the screw threadedportion 52 of sleeve 51. The upper end of the plunger or stem 53 issquared as shown at 55, in order that the usual handle may be securedthereto in the well known manner. The upper end of the casing or body 50is externally screWthreade-d as shown at 56. Co-operating with thethreads 56 are the internal threads 57 on the cap member 58. The cap.member is provided with the opening 59` through which the stem 53passes, l

packing material 60 being provided about the stem 53 to prevent waterpassing upwardly through the cap member. It will be noticed that the capmember 58 overlies the upper end of the sleeve 51 and consequently whenthe cap member 58 is screwed down into place the sleeve 51 is forceddownwardly, thus bringing the tapered portion 61 of the removable valveseat firmly into engagement with the beveled portion 62 of the diaphragm63, thus providing a water tight connection between the bevel side ofthe removable valve seat and the diaphragm.

Secured to the lower end of the plunger 53 by means of the cupped washer64 and nut 65 is the valve washer or gasket 66. The valve washer 66 isbrought into and out of engagement with the valve seat 67 bylongitudinal displacement of plunger 53, caused by the interaction ofthe screw threads 52 and 54 upon rotation of the plunger.

From an inspection Vof Figure 1, it will now be evident that if thefaucet becomes defective, by simply unscrewing the cap 27, the movableelement carried by the sleeve' 17 may be moved out of position. Then byremoving the nut 36 and removing the valve washer, a new valve seat maybe readily placed in position and a new washer placed upon the valvestem. To assist in removal of the nut 36, it may be found desirable toremove the end 33 of the plunger from the bore 32 and place a nail orlike device through the hole 41 to prevent the plunger rotating with thenut.

This arrangement not only permits the change of parts to be ouickly andeasilv made, but provides a replaceable valve seat, which in thepreferred embodiment may be stamped from sheet metal, thus being eX-ceedingly cheap and permitting the valve seats to be furnished of goodmaterial at a price only slightly in excess of the cost of the valvewashers.

It will be readily seen that the valve seat and washer of the form ofthe device shown in Figure 5, are removable just as readily as in theform shown in Figure 1.

While in the drawings and in the above description the removable seathas been shown and described as formed of sheet metal, it is to beunderstood that applicant contemplates forming this seat in other ways,as by machining, also other modifications in the details of theinvention are contemplated. The invention should therefore be limitedmerely by the scope of the appended claims.
